Newbie(?) trouble with wyeadblock.

Quick question: I copied wyeadblock's adblock .so to /urs/lib/vimb (the extension directory) but I'm still getting ads. What possible things could have I done wrong and any possible fixes? (I installed wyebadblock-git 170.529a5ee-1 through AUR) My example is: https://tmuxcheatsheet.com

Perhaps wyeadblock only blocks certain kinds of advertisements?

Also if this is the wrong place to ask pls point me where to ask this :)
